Airflow meters

In engineering, the airflow or air flow is a measurement of the amount of air per unit of time that flows through a particular device.[1][2]

The amount of air can be measured by its volume or by its mass. Typically it is measured by volume, but for some applications it is necessary to measure it by mass, as air is a gas and therefore its volume can vary with temperature.
